I'm a bit shocked at that thread myself, totally uncalled for. C3po interesting??
This puzzles me too. You're against additives yet use A-Rx, and please don't tell me A-Rx is not an additive. You do add it into oil don't you? No valid testing or data for it either. Unless you believe the website or info presented here about it. With all the controversy surrounding the product if I were a newcomer looking for something to clean an engine with, I'd look at a different product. JMO

Compared to how much oil add makers spend to make it, then advertise it. But never get around to having it pass muster.
Thus, no oil company that I'm aware of, and certainly no car maker, recommends using additives.
But if not, and I'm one of those who doesn't, a quality oil/filter and a reasonable OCI should be more than sufficent.
Why should I dilute the additives of Mobil 1 with unproven additives?
